Take a Stand ! était une intervention à composantes multiples en milieu de travail qui réduisait le nombre de personnes assises parmi les employés de bureau. Cette étude visait à déterminer si l’effet de Prendre position ! différait d’un sous-groupe à l’autre.
Objective: Take a Stand! was a multicomponent workplace-based intervention reducing sitting among office-workers. This study tested whether the effect of Take a Stand! differed across subgroups. Methods: A cluster-randomized controlled trial with objectively measured sitting-time as primary outcome evaluated Take a Stand! Main analysis was reanalyzed in strata defined by four levels of preselected factors: socio-demographic (e.g. sex); health-related (e.g. smoking); work-related (e.g. workhours); and psychosocial (e.g. motivation to change sitting). Results: No notable differences in the effect was observed: across all assessed subgroups sitting time was ∼60 min less after 1 month and ∼40 min after 3 months in intervention as compared to control group. Conclusion: There was no differential effect of Take a Stand! indicating that the intervention was effective in all groups. This knowledge is advantageous when disseminating similar interventions to different populations of office workers.
